users ewe I MILK'BOTTLE WITH orniv BOTTOM.

.Application filed April 19,1926. Serial No; 103,110.

This invention relates to extremely new and useful improvements in bottles, and more particularly'to those which are used to contain and in which to transport milk, and the object of my invention is to construct a bottle which, having a detachable bottom,

will permit of perfect cleansing and there erence to the accompanying drawings in which: I I I Fig. 1 1s a perspectlve view of this 1m proved bottle. I v i v Fig. 2 is a vertical section throughthe center of the bottle. I

Fig. 3 is a vertical section through a modified orm of this invention. I

And Fig. 4: is a fragmentary sectional View of a further modified form.

Referring more in detail to the drawings in whichsimilar reference numerals designate the corresponding parts throughout the several views it will be seen that i The numeral 6 designates the main body of the bottle, the side walls of which terminate as at 7, thereby rendering the bottle bottomless, and adapted to receive a plug or the like.

The lower interior surface of the sidewall 6 is provided with threads 8 and is recessed to an extent to provide a surface 9v which will frictionally lock with the relatively disposed surface 10 of the plug 11,

radial surface 13 of the same is serrated orv knurled to facilitate gripping.

In the preferred embodiment ofthis; in-

vention as illustrated in Fig. '2 the upper surface 12 of the plug 11 or the surface adapted to form the interior bottom of the bottle, is concave'd, to eliminate any angular corners-and thereby reduce the possibility of corrosion.

' The modified formof this invention as disclosed i'n'Fig. 3' is of much simpler con struction, however, the principle is the same as will be obvious, the threads 8 are adapted to receive the relatively threaded plug 11, but-the frictional locking surfaces are somewhat removed, being established by the confliction of the lowersidewall surface 14' of the bottle and the upper surface 15 of the gripping flange 13 of the plug.

In the further modified form, Fig. 4, a somewhat different construction'is employed to seal the open bottom of the-bottle, the threads 16 being produced in the lower exterior surface of the bottle sidewall 6and adapted to receive the'relatively threaded cap member 17 andto eliminate all possibility of leakage from the bottle, a suitable washer 18 or the like is adapted;

It willbe obvious from the foregoing de-- scriptionthat this invention'is a great improvement in bottle construction and moreparticularly to bottles adapted to contain and in which to transport milk, and whilethe preferred embodiments of the invention have been disclosed it is to be understood that minor changes in the details of, construction, combination and arrangement of co-operating elements may be resortedto within the scope of what is claimed without departing from the spirit of'the invention.

' What is claimed is 1. A milk bottle comprising a body hav ing an open bottom provided with interior screw-threads, said'threads being recessed relative to the interior wall of said body pro- 1 vidinga radial surface attheend" of the I threads, and a plug having exterior screwthreads recessed relativeto the outer periphery of the plug, adapted t'o-threadedl'y engage the threads of said body, whereby an even joint is effected between the inner Walls of the p1ug' and body.

milk bottle comprisinge body having an open bottom, provided with interior screw-threads, substantially recessed relative to the interior wall of said body and a plug having itsupper centralportion concaved and surrounded by an .exteriorly frem the outer periphery of the plug and adapted to threadedly engage the threads of In testimony whereof I aflix my signe ture.
